20080320066 | Cryptographic random number generator using finite field operations - An apparatus and method are provided in various illustrative embodiments for an integrated circuit chip that provides a fast, compact, and cryptographically strong random number generator. In one illustrative embodiment, an apparatus includes an initial random source, and a post-processing block in communicative connection with the initial random source. The post-processing block is configured to receive signals from the initial random source, to apply one or more finite field operations to the signals to generate an output, and to provide an output signal based on the output via an output channel, in this illustrative embodiment. | 12-25-2008 |

20140028348 | Via-Configurable High-Performance Logic Block Involving Transistor Chains - A via-configurable logic block architecture for a Structured ASIC has a plurality of MOSFET transistor chains connected to one another through vias. In one embodiment there are three chains and the first transistor chain is a NFET transistor chain, the second transistor chain is a PFET transistor chain, and the third transistor chain is a NFET transistor chain. The first, second and third transistor chains are formed into devices made of transistors that are selected from a voltage threshold group consisting of LVT, SVT and HVT devices, where the first and third transistor chains are formed into devices from a voltage threshold group that is different from one another. In another embodiment transistor drive strength may be varied in the transistor chains of the logic block. In yet another embodiment both voltage threshold and drive strength may be varied together in a symmetrical manner. | 01-30-2014 |
20140103985 | Digitally Controlled Delay Line for a Structured ASIC Having a Via Configurable Fabric for High-Speed Interface - A Digitally Controlled Delay Line (DCDL) for a Structured ASIC chip is used to delaying input or output signals into or out of core logic in a Structured ASIC. The DCDL has a multi-stage configuration that in a preferred embodiment comprises two fine delay stages for fine tuning the delay using sub-gate delay through an inverter whose delay can be adjusted with parallel CMOS transistors whose gates are biased with a voltage control signal that is thermometer coded. The fine-tune stages are followed by coarse delay stages that use gate-level delay. A DCDL controller outputs control signals that are Grey coded and converted to thermometer coded control signals by a Binary-to-Thermometer Decoder. The DCDL circuit block and accompanying Structured ASIC are manufactured on a 28 nm CMOS process lithographic node or smaller. A high speed routing fabric using a balanced binary tree is employed with the DCDL. | 04-17-2014 |
